The article considers the results of optimization of the main rotor and determines the flight characteristics of a UAV with an optimized main rotor. To achieve this goal, a mathematical model of the helicopter's hovering main rotor was created, which allows you to find the propeller thrust and power consumption depending on the blade profile, blade shape in plan, geometric twist and fill factor.
